CONCEPT
STATEMENT:
A bubble
consists of molecules of water and
soap. Gas is located inside the thin skin of liquid and the outside
forming
what we call a bubble. Bubbles have color because of the reflection of
white
light, which contains waves of different colors that shine on the
bubble. When
a bubble is about to pop, the skin of the liquid or wall of the bubble
is so
thin that the two sets of waves overlap, resulting in the cancellation
of the
color seen. This is called interference
and it appears that the bubble is white during this stage. Elements of
light
and color can be discovered and applied to future concepts of physics,
while
learning about the color spectrum.
Topology,
exploration of the geometrical properties of various shapes,
substances, and
figures, can be found through the experimentation of creating objects
to make
bubbles. Practicality and real life application are learned through
inventing
tools to make different types of bubbles. Surface tension, elasticity,
soap
solution, materials, and shapes are factors in the technology of
bubbles.
PERFORMANCE
OBJECTIVES:
Students will be able to:
- Predict
when a bubble will pop.
- Tell
how old a bubble is.
- Classify
bubble colors and patterns.
- Identify
materials and tools that create bubbles. (ex: A spoon cannot
make a bubble but a mesh screen can make a bubble)
RESOURCES:
- Water*
- 2 one-quart containers of
Dawn and Joy dish-washing liquid*
- 2 cups glycerin*
- 1 or 2 packages of paper
towels*
- 150 drinking straws
- 2-4 five-gallon buckets
for mixing bubble solution
- 1 empty one-gallon
container
- 1 one- or two-cup capacity
measure
- 3 or more squeegees
- 1 plastic squirt bottle
- 8 cottage cheese-style
containers about 16 oz. each
- dish pans for clean-up
drop cloths, butcher paper, and/or a stack of newspaper to absorb spills
- access to a laminator
- file folders to make signs
for tables
* Ingredients for bubble
solution
Bubble Technology - (needed for this specific
activity)
- 2 Dish Pans
- At least 15 pieces of
“junk” to use for bubble-makers, such as strainers, tin cans,
protractors,
paper, mason jar lids, string, drinking straws, tea ball, rubber
stoppers with
holes, flower pot, funnels, strawberry baskets, plastic rings from a
six-pack,
medicine droppers, rope, paper cups, Styrofoam cups, various mesh
screens,
washers, rubber bands, toilet paper, paper towel rolls, aluminum foil,
wire of
different gauges, and springs.
- Important to include items
that will not work like spoons or cups.
Bubble Colors - (needed for this specific
activity)
- 1 black or brown plastic
trash bag (about 2’ by 3’)
- 8 pieces of tagboard (approx.
8.5” x 11”)
- 1 roll of masking tape
- 1 or 2 cottage cheese
containers per table
- 1 pair of scissors
SAFETY
CONSIDERATIONS:
- Make sure
students know not to drink the
solution or put it in their mouth.
- Discourage students from putting their mouths directly on objects.
- Instruct them how to blow a bubble, so they do not inhale or ingest the
solution.
- If soap gets in a
student’s eye, inform them to blink, do not rub them. (If irritation
continues
have the student go to sink, wash their hands, and splash water in
their eyes.)
- Have towels, newspaper,
and other items readily available for spills or excess foam to prevent
slipping
and falling.
- Do not run or even walk fast around the room.
- Solution stays in the bowls and splashing is not allowed for similar
reasons of
causing spills.

The teacher
will have students gather closely together on a carpet or small area.
Teacher will then show the students a traditional bubble container with
a blow stick and ask what it is. Next, a volunteer will come to the
front and blow some bubbles while the teacher asks probing questions. |
1. Are there
any other ways to make bubbles besides using the blow stick? Can you
name any? |
1. Yes there
are other ways to make bubbles. You can use straws. (Students will then
list other possible tools like this.) Possible misconception: You can
use anything round that has a hole to make a bubble. |
|
2. Do bubbles
have color? If so, why? |
2. Yes,
bubbles have colors. Possible Misconceptions: There is color in the
soap. Or everything has a color. [Bubbles have colors because of the
reflection of white light.] |

Explain that
there are two activities they will be doing today. The first is called
bubble technology, where they will experiment with different objects to
see what makes bubbles. The second is called bubble colors, where they
will observe and discover the colors and patterns of bubbles. |
1. What is
the first thing you are going to do at your station?
2. What are
you doing at the bubble technology station?
3. What are
you doing at the bubble color station? |
1. Blow
bubbles. [Read your sign, then do what it says]
2. We try to
blow bubbles. [Learn what objects allow the blowing of bubbles.]
3. We are
looking at colors on the bubbles. [And also classifying the patterns.] |
Divide the
class into groups of four and assign them to a station. There will be
three bubble color stations on one side of the room and three bubble
technology stations on the other side. After twenty minutes at one
station a bell will be rung and the students will switch to the other
station on the other side of the room. Also I will explain the signs
that are on the table that give them guided instruction. They will go
to their station, read the sign aloud in unison with a partner, and do
what the sign says or depicts. As the students explore, the teacher
should be walking around the room, asking probing/focusing questions
and offering students help. |
4. What do
you do when you hear the bell ring?
5. Can you
use that object in a different way to make a bubble?
6. Can you
tell how old a bubble is by its color? |
4. Move to
the station that we haven’t done yet.
5. I can wave
the object in the air instead of blowing into it.
6. A bubble
doesn’t have an age. It’s not alive. [A bubble’s age can be seen by the
color it emits. If it is white, then it is older and probably fixing to
pop.] |

After thirty
minutes of exploration, the students will dry off. They will return to
their desks to document their findings in their personal journals for
the final twenty minutes. Students can draw or write in their journals
as the teacher rotates around the room asking probing questions. |
1. Did the
bubble have colors? If so, what colors?
2. Were you
able to find how old a bubble was?
3. Did
anything happen when you blew on the bubbles in the color station? Why? |
1. Yes the
bubble had a lot of colors. They swirled around the bubble.
2. A bubble
doesn’t have an age. [A bubble’s age can be seen by the bubble turning
white.]
3. The colors
moved around because the air you blew on the bubble. [As the bubbles
move from the air, light reflects off of the bubble differently,
producing the shift in colors.] |
Explain what
white light is and show them a prism so that they can visually see
white light in action, then relate it to the bubble colors. |
4. Is white
light reflected in a bubble? |
4. No,
because the light is white. It doesn’t have color. [Yes, white light is
reflected in a bubble because white light is the spectrum of colors.] |
Discuss which
objects did or did not make bubbles and why. |
5. What did
we find is the best tool to make a bubble? Can you draw it in your
journal?
6. Why do you
think this bubble maker worked the best? |
5. I liked
the straws because you could control how big you blew a bubble by how
slow or fast you blew into the straw.
6. Bubbles
like wet objects and I was able to get the whole object wet. They also
like for air to be able to blow into them and these objects allowed
this. |

Misconceptions |
As the
students have seen what does and does not create a bubble, ask the
students to draw/create a machine that makes a bubble big enough to
carry them inside. |
1. Why would
your machine work? |
1. I was able
to make the biggest bubbles with the large wire, so I combined more
wire to make a bigger opening to make a bubble. |
To add real
world application, the teacher could also discuss color in other
objects like the rainbow. |
2. Is there a
similarity between a rainbow and a bubble? |
2. No, a
rainbow is in the sky and doesn’t have soap. [The similarity between a
rainbow and a bubble is how we can see the color.] |

Misconceptions |
Explain to
the students that the next day we will be talking about the discoveries
they have made in groups and as a class, so they need to document their
findings in their journals as best as they can. |
1. Were you able to document what
colors you saw?
2. Can you
write or draw the stages of a bubble’s age?
3. Did the
bubble loose color because it was old? |
1. I made
this bubble then colored how I saw the patterns.
2. I made
four different bubbles and showed how the bubble lost color as it got
older.
3. Yes, it
lost color because it got old, just like a person’s hair turns white as
they get older. [The bubble turns white because the soap film is
thinning and light is not reflecting off of it, so that colors can be
seen.] |
Also, that
the teacher will be checking their journals periodically to see what
they have discovered (for mastery of the performance objectives). |
3. How did
you draw/write, which objects made a bubble? |
3. I put all
the objects that couldn’t make a bubble on this page and the objects
that could on this other page. |
